Using the Yakima HighRoad Bike Rack is a breeze. First, make sure your roof rack is suitable as it won't work with square bars deeper than 38mm. Use the tool - free, universal mounting hardware to attach the rack to your roof rack. Then, place your bike on the rack. The new wheel hoop, which fits 26” to 29” wheels and 23 mm to 3.25” tyres without adjustment, will hold the wheels. Turn the TorqueRight™ knob to secure the bike precisely. There's no need to remove the wheels and it won't touch the bike frame, so it's safe for carbon fibre and custom - painted bikes. You can add your own lock to the integrated lock loop, and it also comes with SKS Locks for extra security. As for maintenance, keep it clean after each use. Check the mounting hardware and the TorqueRight™ knob regularly to ensure they're in good condition. If you notice any signs of wear, contact Yakima for replacement parts.
